•
alarm is not active and
•
FAULT RESET is pressed
Ctrl HeartBeat
Output signalizes Watchdog Reset. In a healthy state it blinks at 500ms : 500ms rate. When Watchdog
Reset occurs, it stops blinking.
Stop Pulse
Output is active for 1 second after
Stop Solenoid
output activation. This signal is sent to ECU in case
of engine stop request.
ECU Comm Error
The output is an inversion of binary output
ECU Comm Ok
, i.e. the output is closed when ECU is not
communicating and all values from ECU show #####. Communication error causes stop of the engine.
BI1..7 Status
* IOM BI1..7 Status
The outputs give an information about the assigned binary input.
In case the assigned binary input is configured to alarm type, then the output closes when the alarm
activates. It opens if
•
alarm is not active and
•
FAULT RESET is pressed
In case the assigned binary input is configured to any control function, the output propagates the state
of the input.
* AL IOM AI1..4 Wrn
Output closes if warning alarm on the appropriate IOM/PTM analog input activates.
The output opens, if
•
alarm is not active and
•
FAULT RESET is pressed
* AL IOM AI1..4 Sd
Output closes if shutdown alarm on the appropriate IOM/PTM analog input activates.
The output opens, if
•
alarm is not active and
•
FAULT RESET is pressed
ECU Comm OK
If the ECU is not communicating and all values from ECU show #### the output is not active. If the
ECU communicates the output is active.
ECU YellowLamp
The output copies warning information from ECU.
ECU Red Lamp
The output copies shutdown information from ECU.
ECU PowerRelay
The output closes at the beginning of prestart and opens if the engine shall be stopped.
This output can be used to indicate when the ECU should be powered up i.e. only while the engine is
running.
This output also influences evaluation of communication failure with ECU and related FLS alarms from
analog inputs read from the ECU. If the output is configured (which means configured on physical
binary output or VPIO output), the issuing of communication error is blocked during Prestart and
Stopping procedure as shown in the picture.
